A country and discipline pair appears here when the discipline is substantial across the corpus but thin in that country. Measured by location quotient— the country’s share of a discipline against the corpus share — so it reflects composition rather than size.
Only countries with at least 2 000 subject assignments are included: below that, an absence is sampling noise rather than a signal.
